Create Section Flat/Perpendicular

[COLOR=#333333]Hi there, I have a little confusion on creating a section. I have couple of piping and equipment on my view. Im planning to create a section a certain equipment, ex. a pump, i create i by create-view-section flat, and pick a position and apply. but when i update all the changes all the drawing inside the view has been cut to el 2000. My plan is to cut or section only the pump to el 2000. but the whole drawing sectioned to el 2000. how can i do this? hope you can help me.[/COLOR]

this method will apply section to all the elements in that drawlist.

to achieve this you better to have two different views and drawlists
